Y4008 Powered Multi-parameter Ecosonde
Yosemitech Y4008 Powered Multi-parameter Ecosonde is designed for long-term underwater unmanned monitoring scenarios, integrating multi-parameter measurement, autonomous power supply, and data storage. The device is equipped with a high-performance data acquisition unit and a high-efficiency battery system. Once deployed underwater, it automatically samples and records water quality data in situ at preset frequencies. Upon retrieval, the complete monitoring data can be read directly. With its high performance, flexible self-contained design, and robust in-situ data acquisition capabilities, the detector is widely used in marine environmental monitoring, underwater engineering inspection, marine ecological research, and other fields.
- Self-powered and self-contained—no external power or cables needed.
- Deploy and go: fully autonomous operation reduces setup and maintenance effort.
- 60+ days of continuous operation on a single charge (typical sampling). Ideal for long-term, unattended field monitoring.
- Internal SD card stores up to 150,000 full datasets—over 3 years of continuous data.
- Titanium alloy housing: IP68 waterproof and rated to 200 m depth. Highly corrosion- and pressure-resistant.
- Plug-and-play compatibility with Yosemitech multi-parameter sondes. Electrodes install and swap in seconds.

pH:
Changes in pH in surface water quality affect the ability of algae to take up oxygen and the sensitivity of animals to food intake.
Conductivity:
mainly measures the electrical conductivity of water and monitors the total ion concentration in the water body. Contains a variety of chemicals, heavy metals, impurities and so on a variety of conductive material total.
Dissolved oxygen:
DO in surface water in addition to the usual water sulfide, nitrite, ferrous ions and other reducing substances consumed, but also by the respiration of microorganisms in the water as well as organic matter in the water by the oxidative decomposition of aerobic microorganisms consumed. Dissolved oxygen is an important indicator for surface water monitoring, and is an indication of whether the water body has the ability to self-purify.
Turbidity:
The turbidity value is a visual reflection of the turbidity of the water body. Turbidity is mainly caused by the insoluble substances in the water, insoluble substances including sediment suspended in the water, corrosive substances, planktonic algae and colloidal particles. Reducing turbidity also reduces bacteria, coliform bacteria, viruses, cryptosporidium, iron, manganese, etc. in the water.
Temperture:
Changes in surface water temperature can have a significant negative impact on aquatic wildlife, affecting biological growth and the rate at which fish and shrimp species feed, as well as the timing and efficiency of their reproduction.
Yosemitech supply two types of Multi parameter Water Quality Sensor and one type of Handheld Multi parameter Water Quality Meter. Our multiparameter water quality sensor & meter price is affordable with high quality.
